1) the model explains the hydrogen atom only
2) couldn’t explain why the electrons are stable and why they rotate like planets
3) uncertainty principle ( you can not pin point the exact location and speed at the same time with high accuracy)]]> 2018-05-08 08:07:50 UTC https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813110 https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813478 Because the mass conveted to energy to the two nuclus ]]> 2018-05-08 08:10:13 UTC https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813478 mananmini113 https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813646 This task is bohring😴]]> 2018-05-08 08:11:19 UTC https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813646 https://padlet.com/jafar_abdallah/zv31u9usvqhw/wish/258813774 Electrons are orbiting in several orbits
